T 425


Anti-slip dispersion for loose-lay carpet tiles


A very low-emission, anti-slip tackifier for the easily removable installation of loose-lay carpet tiles and modules equipped with:

  • A smooth, heavily coated backing (e. g. PVC)
  • Or a textile backing such as felt or fleece.
  • Ceresit T 425 can be used on
  • double floors or raised access (e.g. made of screed,
  • plywood or metal),
  • firmly adhering existing coverings (e.g. PVC/CV,
  • linoleum, stone floors)
  • And on all other substrates ready to receive flooring in commercial and public areas as well as residential areas.

If required, the coverings can be removed and fixed repeatedly. Ceresit T 425 meets the highest requirements for indoor air quality and environmental compatibility.


  • Ideally suited for loose-lay tiles with PVC or textile backing
  • Replacement of single tiles possible
  • Prevents slipping and carpet tile movement
  • Ergonomic application by roller

Step by step


Substrates must comply with the requirements of ATV DIN 18 365 “Flooring work”, BS CP 5325 or 8204 or comparable national standards. In particular, they must be clean, free from structural defects, firm, dry and free of substances which may impair ad hesion. After proper mechanical pretreatment (e.g. grinding and vacuuming), prepare the substrate with suitable Ceresit primers and levelling compounds so that it is ready for covering. Before using Ceresit T 425 on very absorbent substrates, prime them with Ceresit R 766 Multi-Purpose Primer (in proportion to 1:1 with water diluted). Thoroughly clean smooth, old coverings and metal surfaces.


Shake the content of the canister well before use and fill it into a clean bucket. Do not pour it directly onto the substrate. Apply a thin and uniform coat of Ceresit T 425 over the entire surface area using a fine-pored foam roller. Use a paint grid to wipe off excess product and avoid the formation of puddles. Prevent the product from seeping into the joints of raised floors. Installation of conductive carpet tiles In some places, conductive carpet tiles are sometimes installed to prevent the build-up of electrostatic charge on people. Generally, the intrinsic conductivity of the carpet tiles is sufficient. To support this effect and connect the tiles with each other, install a copper strip lengthwise underneath every third row of tiles after the T 425 coat has dried. Make sure there is direct contact between the copper strip and the underside of the flooring. Connect the front ends of the strips with crossstrips. Afterwards, install the carpet tiles as described above. Wait until the T 425 film is completely dry before beginning to install the carpet tiles. Otherwise, damagefree removal of the tiles will not be possible.
